基于四参数换档规律的工程车辆智能控制技术

In the early shift schedule research, the power of engine that oil pump consumes was considered as a constant, so it can not reflect the change of power that oil pump consumed. In order to solve this problem, this paper provides a method of intelligent control based on four-parameter shift schedule aiming at improving efficiency of torque converter. A set of electronic control unit with DSP of automatic transmission is developed. Control experiments are carried through on test-bench of engineering vehicle electronic control. The results of experiments show that the structure and control algorithm of intelligent control system put forward are feasible and effective, it could exactly and reliably realize an automatic shifting according to changed working conditions, And could maintain the high efficiency of torque converter.
